Strange safe level change

[Tom]

hello,

Well I'm mailing about a problem I'm having while using the rails
framework, since it does seem to be a ruby problem I thought I might
as well post here

I have a security level problem, for unknown reasons it switches from
level 0 to level 4 and then provoke some error related to the
security level...

I have a plugin we developed I that uses a lot of method.call and
apparently according to a post at technoweeny rails forum, this could
be the problem ( http://www.railsweenie.com/forums/1/topics/659 ) ...

Is there any way to resolve this problem without having to stop using
method.call (we don't really want a major rewrite) ? What exactly is
the problem and why does it happen?

I would be very grateful for your help...

$SAFE is switched when you assign to it, never at any other time.

You have code like $SAFE = 4 in your program somwhere. Use grep to
find it.

Typically $SAFE = 4 is only set in a spawned thread since its so
strict its rarely useful outside of sandboxing dangerous code.
